13. : Evaluation of the sealing provided by resin-based endodontic filling materials and analysis of the expression of metalloproteinases in human and bovine dentin matrix / Avaliação do selamento do conduto radicular por materiais obturadores endodonticos resinosos e analise da expressão de metaloproteinases na matriz dentinaria humana e bovina
Restorative strategies involving dentin bonding have been increasingly applied to endodontics. The first study evaluated the immediate and long-term sealing ability of adhesive versus conventional endodontic filling materials and investigated the influence of a coronal seal on leakage rates. After chemo-mechanical preparation/irrigation, human roots were fil

15. Dry material losses and qualitative evaluation of corn grain stored in hermetic units / Determinação da perda de matéria seca e avaliação qualitativa de grãos de milho armazenados em bolsas herméticas
A significant increase in the grain sector has been observed over the last few years, leading to the expansion of the balance of trade. However, in various Brazilian States, storage systems are composed of old structures, precarious for storage which end up compromising the quality of the product during storage. In order for the sector to increase exports an

16. Deterioração controlada de sementes de tres hibridos interespecificos de capim elefante x milheto / Controlled deterioration of seeds of three interespecific hybrids of elephant grass x pearl millet
The interespecific hybrid Pennisetum purpureum (elephant grass) x P. glaucum (pearl millet) has been developed aiming to get the rusticity and high forage production of elephant grass and the high production of pure seeds of pearl millet. However, it revealed low phenotypic uniformity (around 50.0%) as well as low pure seed production (5 -10.0%). A recurrent

17. Influence of storage time of refrigerated raw milk on the presence of CMP (caseinomacropeptídeo) / Influência do tempo de estocagem de leite cru refrigerado sobre a presença de CMP (Caseinomacropeptídeo)
With the objective to evaluate the influence of the stockage time on the presence of CMP (caseinmacropeptide) in raw milk the raw material after reception for the dairy industrie was cooled, 4 C, and stored in 20.000 L isothermal horizontal tank. The tank remained sealed up during the 72 hours of stockage and in this period the access to this only for collec

18. Thermal and moisture content on storability and seed dormancy releasing of Brachiaria brizantha (Hochst. ex A. Rich.) Stapf / Efeitos termicos e de graus de umidade constantes na liberação da dormencia de sementes de Brachiaria brizantha (Hochst. ex A. Rich) Stapf
As sementes do gênero Brachiaria apresentam um mecanismo duplo de dormência, mais pronunciado em sementes recém colhidas, conduzindo a valores abaixo dos de viabilidade obtidos pelo teste de Tetrazólio e, deste modo, dificultando a tomada de decisões para o armazenamento, comercialização e fiscalização do comércio dessas sementes. Utilizando-se a t

19. Effect of addictives on crystallization of ice cream. / Efeitos de aditivos na cristalizaÃÃo de sorvetes
The present study aimed to evaluate the influence of addition of carrageenan and calcium on the process of ice recrystallization in the ice cream mass. A basic mixture was prepared and divided into two parts; to one of them, carrageenan was added to attain the proportion of 0,05 percent of the total volume. Subsequently, each one of the two parts were subdiv

20. Desiccation tolerance and sensitivity in Medicago truncatula and Inga vera seeds
Orthodox seeds acquire desiccation tolerance (DT) during their development which enables them to pass through the phase of maturation drying by the end of their development and enter a state of quiescence. After harvesting, these seeds can be dried further and stored for the long-term without significant loss of viability. On the other hand, there are many s

21. Influencia de irrigantes endodonticos na resistencia de união de um adesivo autocondicionante a dentina da camara pulpar
Chemical irrigants and medications used in endodontic therapy may have an adverse effect on bonding to pulp chamber dentin. The aim of this study was to evaluate in vitro the influence of endodontic irrigants on the bond strength of a self etching adhesive system to bovine teeth pulp chamber dentin. Seventy crowns of bovine mandibular incisors were cut to ex

22. Equações de viabilidade para sementes de Eucalyptus grandis W.Hill ex Maiden e Pinus taeda L
The knowledge of seed performance under storage conditions is extremely important to determine its storability potential. The main aim of this work was determine the best methodology to achieve the survival and preservation of Eucalyptus grandis W.Hill ex Maiden and Pinus taeda L. seeds, under controlled storage conditions, through the detection of the viabi

23. Study of the stability of sliced cooked ham in modified atmosphere. / Estudo da estabilidade de presunto cozido fatiado em atmosfera modificada.
The purpose of this study was to evaluate the efficiency of packaging systems with modified atmosphere to preserve the quality of sliced cooked ham. Thus the quality stability of the product at 4 +/_:t 1°C, packed in a gas barrier package with three kinds of modified atmosphere (100% CO2, 60% CO2/40% N2 and 25% CO2 I 75% N2), was studied. The shelf-life of

24. Estabelecimento da vida útil de hortaliças minimamente processadas sob atmosfera modificada e refrigeração. / Establishing the shelf life of minimally processed vegetables by modified atmosphere and refrigeration.
The postharvest losses of horticultural products justify the adoption of preservation techniques. Once these products are processed, they add value to the primary products and they become convenient to the consumer. This research had the purpose of defining the methodologies for minimal processing of carrot, green pepper and mixed salad of potato and string
